Yep, I know that.

I'm just wondering why I have to setup an entirely separate 
infrastructure of H.323 Gatekeepers and configure "zones" and all that 
jazz for the Polycom video units to register to.  The Polycom's employ 
H.323 gatekeeper discovery, so why can't the Call Manager's answer, 
perform IP <-> E.164 mapping, determine if the Polycom can use IP to 
connect to another Polycom over the LAN/WAN, etc, etc?  Seems like 99% 
of that functionality is already _in_ CallManager.
